Has anyone here seen save batteries leak on the board? I have 3 dead carts now. One definitely has a battery, I'm not sure of the other two:

Landstalker (Genesis)
Mick & Mack as the Global Gladiators (Genesis)
Paper Mario (N64)

I cleaned all of them a lot, even using metal polish which worked on a few other stubborn games.

I've seen some goofed carts too, they did boot up but didn't play:

Kool Aid Man (2600) - Screen came up but nothing worked.
Star Wars: Jedi Arena (2600) - Maybe I didn't know how to play this but the lightsaber only seemed to go in one direction; northwest-ish.
